[0002] As an important nutritious drink, the quality and taste of liquid milk directly affect consumers' acceptance. In the process of liquid milk processing, removing excess sodium ions while retaining its nutritional components and flavor is an important technical challenge.

[0003] In the existing sodium removal membrane filtration and concentration of liquid milk, liquid milk is usually fed into a filtration container with a sodium removal membrane, and the sodium removal membrane filters the sodium ions in the liquid milk to obtain high-purity liquid milk without sodium ions. However, when the sodium removal membrane filters liquid milk, the filtration efficiency is low, resulting in low production efficiency of liquid milk.

[0004] Therefore, a selective sodium removal membrane filtration and concentration device for liquid milk is now developed, which can improve the filtration efficiency of the sodium removal membrane filtration column for liquid by pre-treating the liquid and increasing the flow pressure of the liquid milk, and improve the production efficiency of liquid milk. Content of the Utility Model

[0005] In order to overcome the defect that the filtration efficiency of the existing sodium removal membrane filtration and concentration device for liquid milk is low when the sodium removal membrane filters liquid milk, resulting in low production efficiency of liquid milk, the utility model provides a selective sodium removal membrane filtration and concentration device for liquid milk, which can improve the filtration efficiency of the sodium removal membrane filtration column for liquid by pre-treating the liquid and increasing the flow pressure of the liquid milk, and improve the production efficiency of liquid milk.

[0006] The technical solution is: a selective sodium removal membrane filtration and concentration device for liquid milk, including a connecting chassis, a feed pipe, a connecting pump, a first connecting pipe, a rotating pipe and a filtering component.

Second connecting pipes are connected to the lower sides of the first connecting flanges. The second connecting pipes are all located outside adjacent second spiral plates. Drain pipes are connected to the front sides of the lower parts of the second connecting pipes. Sodium removal membrane filter columns are slidably and snap-connected in the drain pipes.

[0009] Furthermore, clamping grooves are formed in the sodium removal membrane filter columns, and clamping posts are arranged in the second connecting pipes.

[0010] Furthermore, it further includes a third connecting pipe, a second connecting flange, and a first discharge pipe. A third connecting pipe is connected to the rear part of the connecting chassis. A plurality of second connecting flanges are connected to the upper sides of the left and right parts of the third connecting pipe.

[0011] Furthermore, it further includes a fourth connecting pipe, a third connecting flange, and a second discharge pipe.

A plurality of third connecting flanges are connected to both the left and right sides of the fourth connecting pipe.

Detailed implementation mode

[0019] The technical solution of the present utility model will be further described below in conjunction with the accompanying drawings.

[0020] A selective sodium removal membrane filtration and concentration device for liquid milk, as Figure 1 and Figure 2 shown, includes a connecting chassis 1, a feed pipe 2, a connecting pump 3, a first connecting pipe 4, a first spiral plate 40, a rotating pipe 5 and a filtration component. Two first connecting pipes 4 are connected to the front part of the connecting chassis 1 on the left and right. A feed pipe 2 is connected between the lower parts of the first connecting pipes 4. A connecting pump 3 is connected to the left side of the lower part of the feed pipe 2. First spiral plates 40 are rotatably connected in the first connecting pipes 4. A rotating pipe 5 is rotatably connected to the upper side of the first connecting pipes 4. A filtration component is provided on the rotating pipe 5.

[0021] As Figure 1 、 Figure 3 and Figure 5 shown, the filtration component includes a first connecting flange 6, a second spiral plate 7, a second connecting pipe 8, a drain pipe 80 and a sodium removal membrane filtration column 9. Four first connecting flanges 6 are connected to the rotating pipe 5. Second spiral plates 7 are rotatably connected to the first connecting flanges 6. Second connecting pipes 8 are connected to the lower sides of the first connecting flanges 6. The second connecting pipes 8 are all located outside the adjacent second spiral plates 7. Drain pipes 80 are connected to the front sides of the lower parts of the second connecting pipes 8. Sodium removal membrane filtration columns 9 are slidably and snap-connected in the drain pipes 80. Clamping grooves are opened on the sodium removal membrane filtration columns 9. Clamping columns are provided in the second connecting pipes 8 for easy clamping.

[0022] As Figure 1 、 Figure 4 and Figure 5As shown, it further includes a third connecting pipe 10, a second connecting flange 100, a first discharge pipe 101, a fourth connecting pipe 11, a third connecting flange 110, and a second discharge pipe 111. A third connecting pipe 10 is connected to the rear of the connecting chassis 1. Four second connecting flanges 100 are connected to the upper sides of the left and right parts of the third connecting pipe 10. A first discharge pipe 101 is connected to the rear side of the third connecting pipe 10. A fourth connecting pipe 11 is also connected to the rear of the connecting chassis 1. The fourth connecting pipe 11 is located below the third connecting pipe 10. Four third connecting flanges 110 are connected to both the left and right sides of the fourth connecting pipe 11. A second discharge pipe 111 is connected to the rear side of the third connecting flange 110.

[0023] When using the present utility model, first place the connecting chassis 1 in the selective sodium removal membrane filtration and concentration area of liquid milk. Then, dock the feed pipe 2 with the transportation pipeline of liquid milk so that the liquid milk enters the feed pipe 2. Next, turn on the connecting pump 3 to pump the liquid milk from the feed pipe 2 into the first connecting pipe 4 and then flow into the rotating pipe 5. When the liquid milk passes through the first connecting pipe 4, it will cause the first spiral plate 40 to rotate. Under the rotation of the first spiral plate 40, the liquid milk is evenly mixed in the first connecting pipe 4, and at the same time, the flow rate and flow pressure of the liquid milk are increased. While feeding the liquid milk, snap the sodium removal membrane filtration column 9 into the second connecting pipe 8, and then connect the second connecting pipe 8 to the first connecting flange 6 so that the second spiral plate 7 is located inside the sodium removal membrane filtration column 9. Then, rotate the rotating pipe 5 to drive the second connecting pipe 8 to rotate, so that the second connecting pipe 8 moves above the third connecting pipe 10. Then, dock the second connecting pipe 8 with the third connecting pipe 10 through the second connecting flange 100, and dock the drain pipe 80 and the fourth connecting pipe 11 through an external pipeline and the third connecting flange 110. Thus, after the liquid milk flows into the rotating pipe 5, it then flows into the second connecting pipe 8, and the liquid milk is filtered by the sodium removal membrane filtration column 9. The internal sodium ions in the liquid milk are filtered through the sodium removal membrane. The liquid milk after sodium removal and concentration flows into the fourth connecting pipe 11 through the drain pipe 80 and is then discharged and collected from the second discharge pipe 111. The residues generated by filtration remain in the second connecting pipe 8, then flow into the third connecting pipe 10 and are discharged and collected from the first discharge pipe 101. When the liquid milk flows into the second connecting pipe 8, it causes the second spiral plate 7 to rotate. When the second spiral plate 7 rotates, the deposits on the sodium removal membrane filtration column 9 are scraped off, maintaining the permeability of the sodium removal membrane filtration column 9 and preventing the sodium removal membrane filtration column 9 from being blocked, improving the filtration efficiency of the sodium removal membrane filtration column 9. And when the second spiral plate 7 rotates, it can increase the flow rate and flow pressure of the liquid milk, improving the filtration efficiency and quality of the sodium removal membrane filtration column 9. When it is necessary to replace and clean the sodium removal membrane filtration column 9, the second connecting pipe 8 can be disassembled from the third connecting pipe 10, then rotate the rotating pipe 5 to disassemble the second connecting pipe 8 from the first connecting flange 6, and then take out the sodium removal membrane filtration column 9 for cleaning and replacement. Thus, it can play a role in pre-treating the liquid and increasing the flow pressure of the liquid milk, improving the filtration efficiency of the sodium removal membrane filtration column 9 for the liquid, and improving the production efficiency of liquid milk.

[0024] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
